Lipid X is a 2,3-diacylglucosamine-1-phosphate that serves as the monosaccharide precursor of lipid A, possessing both LPS antagonist and weak agonist activities. Lipid X exerts protective effects by inhibiting tumor necrosis factor production, monocyte procoagulant activity, and neutrophil priming. Lipid X may induce transient pulmonary hypertension, neutropenia, and mild pyrogenic effects in laboratory animals. Lipid X has low toxicity and no in vitro antibacterial activity, but it significantly reduces mortality following Gram-negative bacterial infection and endotoxin exposure. Lipid X tends to accumulate in liver tissue, binds to circulating cellular components, and can be converted to lipid Y through transesterification. Lipid X can be used in research on Gram-negative bacterial sepsis, endotoxemia, and associated pulmonary hypertension .

Pre-vitamin D3 decanoate is a derivative of vitamin D3 that can be converted into the active form of vitamin D in the body. Pre-vitamin D3 decanoate is first converted to 25-hydroxyvitamin D3 in the liver and then further converted to 1,25-dihydroxyvitamin D3 in the kidneys. During preparation, vitamin D3 may react with the triglycerides in the formulation to form ester compounds, and this esterification affects the stability and bioavailability of vitamin D3. Pre-vitamin D3 decanoate can be used in the study of certain diseases associated with vitamin D, such as osteoporosis, autoimmune diseases, and certain cancers .

Ac-Asp-Glu-Asp(EDANS)-Glu-Glu-Abu-ψ-(COO)Ala-Ser-Lys(DABCYL)-NH2 (HCV NS3 protease substrate) is a biological active peptide. (This peptide is a HCV protease substrate incorporating an ester bond between residues P1 and P1. Due to ready transesterification of the scissile bond to the acyl-enzyme intermediate, this substrate shows very high kcat/Km values, enabling detection of activity with subnanomolar nonstructural protein 3 (NS3 protease) concentrations. It is widely used for the continuous assay of NS3 protease activity. Substrate cleavage is proportional to the enzyme concentration with a detection limit for NS3 between 1 nM and 250 pM.
